Low-voltage hydrogen production from formic acid: The role of different electrolysis parameters

Journal of Polytechnic, Год журнала: 2025, Номер unknown, С. 1 - 1

Опубликована: Апрель 26, 2025

This study investigates the electrolysis of formic acid for hydrogen production, focusing on effects various parameters and materials. In first phase, experiments were conducted using a single-compartment cell with Pd/Pt electrodes at 20°C. The effect concentration, electrolytes, electrode materials current density was analyzed. highest (5.18 mA/cm² 1 V) achieved H₂SO₄ as an electrolyte. Zn/Zn pair significantly outperformed Pd/Pt, yielding four times higher density. second conditions production low voltage (2 temperature (50°C) optimized. Pure obtained cathode, confirming successful under these conditions. Faradic efficiency reached 92% 2 V, high rate. use cost-effective Zn electrode, along mild conditions, enhances practicality sustainability process. These findings highlight that is promising efficient method pure offering economical sustainable alternative generation.

In this paper, the electrochemical and corrosion behavior of pure titanium (TA1) in simulated Proton Exchange Membrane Water Electrolysis (PEMWE) anodic environment was investigated. condition, potential TA1 −689 mV, with a self-corrosion current density 232.5 μA cm –2 , polarization resistance 125.9 Ω 2 . During potentiostatic at V, maintained approximately 6 mA However, passivation process exhibited instability. Furthermore, has been shown to significantly facilitate formation surface oxides, passive film that formed displays lowest bound water OH − highest content O 2– exhibiting average valence. Notably, dynamic potentials caused transients, among which square wave most remarkable. The shows an just below 2V when fluctuating are applied. interfacial contact (ICR) V slightly higher than square, sine triangular waves. Additionally, high temperature condition PEMWE will aggravate by fluoride ions.
